هدف هذا العمل إلى دراسة تأثير بعض العوامل البيئية من درجات الحرارة ومدة الحفظ على إنهاء ظاهرة توقف التطوّر لدى ذبابة أوراق الزيتون Dasineura oleae F.loew (Diptera : Cecidomyiidae) ، و المتطفل الداخلي Walker Platygaster demades ((Hymenoptera: Platygasteridae . نفّذت سلسلة من التجارب لإنهاءِ هذه الظاهرة لليرقات، بتعريضها لتناوب حراري بين درجة حرارة ملائمة للنشاط (20 ± 1 oم) مع إضاءة طويلة 16 L : 8 D و رطوبة نسبية 75± 5% لفترات مختلفة (15، 30، 60) يوماً، ثم فترة برودة 7± 1 o م و ظلام كامل و رطوبة نسبية 75± 5% لمدة 15 يوماً، و ذلك بدءً من توقف التطور و بعد (30، 60، 90 و 120) يوم.
This work aimed to study the environmental factors influencing growth stopped of olive leaf midge Dasineura oleae F. loew (Dipter: Cecidomyiidae) and its host (Hymenoptera: Platygasteridae) Platygaster demades Walker, such as temperature and reservation period. A series of experiments had been done to end this phenomena of larvae by changing temperatures from suitable temperature at 20±1 °C accompanied with different photoperiods 16 L: 8D and relative humidity of 75± 5% during 15, 30, and 60 days, to low temperature at 7± 1 °C accompanied with complete darkness and relative humidity of 75± 5% for 15 days. This had been done after 30, 60, 90 and 120 days of growth stopped.

Pastrami, manufactured from beef and abdominal fat and of a ratio of 3 meat to 1 fat,
was stored under refrigeration at (4±2 °C) and storage times (0, 15, 30, 60, 120, and 180
days). The effects of storage times on the most important chemical, micr
obiological and
sensory properties of pastrami were investigated.
The results of chemical analyzes showed that the studied pastrami conformed to the
Syrian Standards in terms of the proportion of salt and fat content, and it nearly conformed
to the standards in terms of humidity. The results also showed a slight decrease in the
percentage of moisture, fat and protein, and an increase in each of the acidity, proportion of
total volatile nitrogen, soluble nitrogen and peroxide value in pastrami with the progress of
the storage period at the temperature degree (4±2 °C). The microbial tests showed that
pastrami is free from some sickening organisms especially salmonella and E. coli. It also
showed that the census of the aerobic bacteria, yeasts and fungi was within the limits of the
Syrian standards. The results showed deterioration in the microbial properties of stored
pastrami with the progress of time; pastrami became invalid from a microbial point of
consumption after two months of storage as a result of the big number of aerobic bacteria,
yeasts and fungi. The sensory tests showed deterioration in the organoleptic characteristics
of storage with the progress of time, the deterioration was clear after two months of
storage; pastrami became unacceptable in terms of taste, color, smell and texture.
The research was conducted during the period between May 2014 and May 2015. The field work was carried out in the Astamo area of Lattakia within an orchard planted with citrus and olives in the form of single and adjacent sectors for each
This research discusses the affecting factors of biogas production
in the digester, to define the optimal temperature and suitable
loading rate to achieve high digester biogas production. The
research focuses on the water compressed continuous flo
w
digester (chines model), and the results is presented and illustrated
in suitable tables and curves.
Biological tests were study the pathogenicity of four
local isolates of Beauveria bassiana (Bals) orginated
from, Latakia , Homs ,ICARDA Jableh on third larval age of Bactrocera oleae.
In this research, the quantity of vitamin C which extracted from fresh fruits and
vegetables was evaluate by using titration method with 6-2 Dichloro phenol andovinol, and
studying the effect of conservation and different temperatures (30, 60, 90)
°C which used
in cooking on content of vitamin C for some samples. Also this search included studying of
the effect of iron ions on content tomato, orange and lemon of vitamin C.
The results showed that the concentration of vitamin c in studied samples: parsley,
red pepper, green pepper, lemon, orange and tomato was (8, 22, 36, 144, 175, 133)
mg/100g respectively. Losing of the vitamin was (66%, 65%) when we save the leaves and
stalk of parsley for 24 hours respectively, when exposure the parsley leaves to the
temperatures (30, 60, 90) c° the losing percentage was (24 %, 41%, 62 %), While the
losing was (79%, 65%, 39%) when injected each of tomatoes, oranges, lemons with
dissoluble of iron.
